Definitions

  • the present invention provides a blooming pine oil cleaning composition.
  • the present invention also provides a method of cleaning a surface using the disclosed pine oil cleaning composition.
  • Water-soluble cleaning compositions are commercially important products and enjoy a wide field of utility in assisting in the removal of dirt and grime from surfaces; especially those characterized as useful with "hard surfaces".
  • One particular category of aqueous cleaning compositions are those which provide a "blooming" effect upon being added to water. Such an effect may be described as the change of the water's appearance from essentially colorless and transparent to that of a milky white or milky yellowish white, cloudy appearance upon the addition of an amount of the cleaning composition. This effect is also sometimes referred to as the "break”.
  • Such blooming is highly desirable in such pine oil type water- soluble cleaning compositions as consumer/end user associates cleaning effectiveness with the extent and degree of this blooming upon formation of a cleaning composition.
  • pine oil type water-soluble cleaning compositions which typically include one or more of the following identifying characteristics: containing an amount of one or more resins or oils derived from coniferous species of trees; containing natural fragrances or synthetic fragrance compositions which are intended to mimic the scent of one or more resins or oils derived from coniferous species of trees; a color ranging from colorless to a deep amber, deep amber yellow or deep amber reddish color; generation of a milky or cloudy appearance when diluted with water in dilutions useful for cleaning applications.
  • Such pine oil type cleaning compositions are generally provided in a concentrated composition which is subsequently diluted with water by an end user/consumer to form a cleaning solution therefrom.
  • pine oil cleaning compositions Another important characteristic of pine oil cleaning compositions is phase stability.
  • the composition should be clear and phase stable at temperatures of normal use and storage, before being further diluted with water. There is thus a need for a water-soluble pine oil cleaning composition that possesses the characteristics of phase stability, blooming, and efficient cleaning properties.
  • the present invention provides such a cleaning composition.
